Basic Signal Theory
The purpose of this chapter is to establish the basic definitions and terminology to be used throughout this book and to briefly review material required for the understanding of echo-location from an engineering and mathematical perspective. Accordingly, this chapter contains standard signal processing material that would be covered at the senior under-graduate or early graduate level in electrical engineering. Most of it may be found in standard texts some of which are listed in the references. It is assumed that the reader has some background in linear systems, probability and stochastic processes, vector matrix notation, and is familiar with the conventions used to denote random variables and vectors.
